68Configuration Software and UtilitiesHow EMP Console WorksThe EMP shares use of the COM2 port with the system on the server. When the EMP has controlof the port, the port operates in command mode. When the system has control, the port operates inconsole redirect mode. When connecting to a server, the EMP Console checks to determine themode of the COM2 port. The following discussion covers how EMP Console functions ineach mode:· Command mode is the default COM2 state. In this state, EMP Console communicates with theserver’s firmware, allowing the client to remotely reset or power the server up or down. Theclient can also view the server’s System Event Log (SEL), Field Replaceable Unit (FRU)information, or Sensor Data Record (SDR) table.· In console redirect mode, EMP Console serves as a PC ANSI terminal window forBIOS console redirection. Commands typed in this terminal window are transmitted throughBIOS to the server’s console, and text displayed on the server console is displayed on theEMP Console’s terminal window. In this mode, you can remotely view boot messages, accessBIOS setup, and run DOS text mode applications through the EMP Console’s terminal window.Figure 11. EMP Console in Command State
